The Phospholipase A2 Homologues of Snake Venoms: Biological Activities and Their Possible Adaptive Roles
(2009)
A particular subgroup of toxins with phospholipase A2 (PLA2) structure, but devoid of this enzymatic activity, is commonly found in the venoms of snakes of the family Viperidae, and known as the PLA2 homologues. Among ...
High-density peptide microarray exploration of the antibody response in a rabbit immunized with a neurotoxic venom fraction
(2017-11)
Polyvalent snakebite antivenoms derive their therapeutic success from the ability of their antibodies to
neutralize venom toxins across multiple snake species. This ability results from a production process
involving ...
Biological and proteolytic variation in the venom of Crotalus scutulatus scutulatus from Mexico
(2018-01)
Rattlesnake venoms may be classified according to the presence/absence and relative
abundance of the neurotoxic phospholipases A2s (PLA2s), such as Mojave toxin, and snake venom
metalloproteinases (SVMPs). In Mexico, ...
Venom characterization of the bark scorpion Centruroides edwardsii (Gervais 1843): composition, biochemical activities and in vivo toxicity for potential prey
(2019)
In this study, we characterize the venom of Centruroides edwardsii, one of the most abundant scorpions in urban
and rural areas of Costa Rica, in terms of its biochemical constituents and their biological activities. C. ...
Porcentaje y cifra absoluta de linfocitos T en sangre periférica por el método de rosetas E: estudio de cuarenta adultos sanos
(1985)
Se realizó la determinación del porcentaje y cifra absoluta de linfocitos T en sangre periférica a un grupo de 40 adultos sanos costarricenses, seleccionados de un grupo inicial de 58 voluntarios. Se utilizó un método de ...
Delayed oral LY333013 rescues mice from highly neurotoxic, lethal doses of Papuan Taipan (Oxyuranus scutellatus) venom
(2018)
There is an unmet need for economical snakebite therapies with long shelf lives
that are effective even with delays in treatment. The orally bioavailable, heat-stable, secretory
phospholipase A2 (sPLA2) inhibitor, LY333013, ...
Cell surface nucleolin interacts with and internalizes Bothrops asper Lys49 phospholipase A2 and mediates its toxic activity
(2018)
Phospholipases A2 are a major component of snake venoms. Some of them cause severe muscle necrosis
through an unknown mechanism. Phospholipid hydrolysis is a possible explanation of their toxic action,
but catalytic and ...
Antibody-dependent enhancement of toxicity of myotoxin II from Bothrops asper
(2024)
Improved therapies are needed against snakebite envenoming, which kills and
permanently disables thousands of people each year. Recently developed
neutralizing monoclonal antibodies against several snake toxins have ...
Proteomic and toxicological analysis of the venom of Micrurus yatesi and its neutralization by an antivenom
(2022)
Coralsnakes belong to the family Elapidae and possess venoms which are lethal to humans and can be grouped based on the predominance of either three finger toxins (3FTxs) or phospholipases A2 (PLA2s). A proteomic and ...
Unresolved issues in the understanding of the pathogenesis of local tissue damage induced by snake venoms
(2018-06)
Snakebite envenoming by viperid species, and by some elapids, is characterized by a complex pattern of
tissue damage at the anatomical site of venom injection. In severe cases, tissue destruction may be so
extensive as ...
